A block copolymer is produced from I. 1 to 60% by weight of at least one telechelic diene polymer containing terminal carbonate ester, --OH--, --NH.sub.2 --, carboxylic acid or carboxylic acid ester groups and having a molecular weight M.sub.n of from about 400 to 1300, and II. 99 to 40% by weight of at least one polyamide or polyamide-forming component.

This invention relates to an improved bottom block for vertical DC and EM casting large ingots and billets, particularly ingots having generally rectangularly shaped cross sections which are rolled into sheet and plate. The improved bottom block stably supports the ingot or billet in its downward descent during casting so that the ingot or billet does not move on the bottom block by leaning off center or rocking back and forth. In accordance with the invention, a plurality of drain holes in the ...

A building block has an inner and an outer wall defining a cavity therebetween, the two walls being interconnected by two or more webs positioned intermediate the top and bottom of the block to provide upper and lower horizontal channels. The walls at the top each have a longitudinal projection extending along an inner portion which in a building locates the blocks by being positioned in the lower horizontal channel. The block has two end portions which are either both a female recess or a male ...

A cylinder block comprises an upper block deck disposed along whole the periphery of a cylinder-barrel section to securely connect the cylinder-barrel section with a water jacket outer wall section. The upper block deck is located below the top of the cylinder block and so positioned that its center lies at the level of an uppermost part of the skirt section of a piston which is at a range from TDC to 30 degrees relative to TDC. Additionally, upper and lower water jackets are formed at the upper...

The invention combines a Vee block and angle plate, as used for example by tool makers, into a single article. As shown in FIG. 1, for example, it is possible to maintain much of the versatility of a typical angle plate with that of a typical Vee block, but at greatly reduced cost as compared to that of providing the two separate parts.

The cylinder block comprises an oil pan installation rail which is integral with a skirt section at a lower part of the skirt section. The installation rail is generally in the shape of a quadrangular pyramid whose width and height gradually increase in the direction from the cylinder block front end to the cylinder block rear end. The oil pan installation rail is hollow. Additionally, a transmission installation section is integral with the rear end of the oil pan installation rail and also int...

A one-piece cylinder block for a water-cooled internal combustion engine with two rows of cylinders in a V-arrangement has a longitudinal duct for supplying cooling water. The block is preferably made by a diecasting process. The longitudinal duct is connected to the coolant spaces of the cylinders which are located between a cylinder sleeve and an outer jacket surrounding the latter. The longitudinal duct is disposed between the rows of cylinders in the cylinder block and at least one opening i...

A connector block operatively engages the pins of a terminal assembly in a frictional or other mechanical relationship such that the connector block is securely held in place. When held in place, the connector block overlies the pins such that they cannot be dislodged from the terminal assembly. Connectors located in the connector block provide frictional engagement with the pins while affording electrical access to the terminal assembly.

A specimen block which supports a specimen during inspection by both an optical and a scanning electron microscope, and further supports the specimen during a coating operation to enhance secondary electron and X-ray emission, has a planar base and an inclined surface upon which the specimen is to be mounted. During inspection by the scanning electron microscope, the specimen block is held by a standard specimen block holder and the specimen is held at the angle of the inclined surfaces with res...

A barrier block is disclosed which incorporates an electrical terminal in the form of a hollow cylindrical barrel provided with a longitudinal slot divided into one or more pairs of wire gripping jaws. The barrel is integral with a second electrical contact seatec on a web which interconnects a pair of partition walls. Opposite ends of the barrier block are molded with intermateable channels allowing a plurality of barrier blocks to be intermated and latched together.
